I think there is much more to see in my previous plot for discussion, even if it is 'hardly realistic'.I think there is much more to see in my previous plot for discussion, even if it is 'hardly realistic'.[with this plot referring to]... the mass in the model is the chassis, not the wheel. ... So the impulse is either a force on the chassis, or a displacement at the ground, which have the same response (ratio) for impulse.[and]... I'm pretty sure mass (+ maybe coulomb friction) is the only thing that transmits the 'sudden impact ... at the wheel'...

Yeah we just took the voltages from the accelerometers, then I used them in the logarithmic decay method to find damping ratio etc for the first part..So I don't think we need velocity and displacement?
What I've got to do is use theory to predict the amplitude ratio and phase lag of the mass as a function of the forcing frequency ratio. Then compre the results with the test data. It also says for this test the system response is to be the ratio of, the output displacement of the mass, and the input displacement to the spring, and the phase lag will be considered too. I can't quite get my head around what that means though.
(btw is forcing frequency ratio ω, or is that just forcing frequency?)
Also to write a "1st order linear, constant-coefficient differential equation for the system, with the forced excitation as the forcing function", how is the forced excitation, or anything else for that matter, made the forcing function, or function of the equation? Is it that the equation will be something like x="loads of things multiplied and divided by the thing you want the function to be"?
I'm very new to this so I may not be making much sense or being vague so I do apologise! I appreciate the help :) Any further reading you could recommend to help with this would be good!
